Introduction

The Bible does not specifically address the issue of viewing
pornography, since it didn't really exist at the time the books of the
Bible were written. So, does this mean that it is allowable as a "freedom
in Christ" issue? Can we discern a clear moral teaching based upon what
the Bible teaches about other sexual sins?

Prohibited sex

Several specific sexual acts are forbidden in the Bible. Among these
are homosexuality,1 bestiality (sex with
animals),2 and incest (sexual relations with
close family members, including your mother, sister, niece, aunt,
daughter-in-law, and sister-in-law),3fornication
(sexual relations outside of marriage)4 and
adultery (sexual relations with another person's spouse),5 rape (forced sex),6 and orgies.7
To emphasize the seriousness of these kinds of offenses, the penalty was
death.8 All of these categories are
abundantly represented in pornographic offerings. The only acceptable form
of sexual expression—between a married husband and wife—is virtually
absent. So, virtually all the acts pornography depicts are prohibited
in the Bible. Obviously, one should not be participating in such acts,
even vicariously.

Acts of the mind

Christianity is not just about avoiding sinful physical acts, but also
about mental purity. Actually, this idea did not begin with Christianity,
but originated from Judaism, the belief system from which Christianity
arose. The Decalogue (10 commandments) first delineates the requirement of
mental purity:

"You shall not covet your neighbor's house;
you shall not covet your
neighbor's wife or his male servant or his female servant or his ox or his
donkey or anything that belongs to your neighbor." (Exodus 20:17)

So, the prohibition against coveting specifically prohibits desiring
another man's wife.9 Jesus specifically addressed the question of lusting
after a women who wasn't one's wife, equating it with the physical act of
adultery:

"You have heard that it was said, 'YOU SHALL NOT COMMIT ADULTERY'; but I
say to you that everyone who looks at a woman with lust for her has already
committed adultery with her in his heart. If your right eye makes you
stumble, tear it out and throw it from you; for it is better for you to lose
one of the parts of your body, than for your whole body to be thrown into
hell. (Matthew 5:27-29)

The prohibition against lust is found throughout the New Testament,10
which says that such desires "wage war against the soul."11
James gives an analogy of lust to procreation, in which lust conceives and
gives birth to sin, which results in death.12
Of course, the goal of pornography is to elicit lust, which makes its
consumption a form of sin.

Renew your mind

The Bible makes it clear that our thoughts are subject to the scrutiny of
God.13 It tells us that we are to keep our mind on the
things above, not on the things of the earth.14
Instead of thinking about things of the flesh, which results in spiritual
death, Christians are to set our minds on spiritual matters.15
The mind set on fleshly desires cannot please God, but eventually becomes
defiled as the conscience becomes seared.15, 16
The viewing of pornography by Christians results in a mind that is focused
on lust and fleshly desires, instead of on the things of God. The goal of
the Christian is to not conform to the desires of the world, but to be
transformed by Christ through the renewing of our minds, so that we can do
the perfect will of God.17

Your body is not yours

Christians are to avoid all forms of sexual sin, since the Christian's
body is indwelt by the Holy Spirit.18 Paul
says that the body is meant for the Lord and not for sexual immorality.19
Since Christians are redeemed (bought back with a price—which was the
sacrifice of Jesus Christ) we no longer "own" our bodies,
since they have been purchased by God.20 Not
only are Christians to avoid sexual sins, but we are to avoid those who
claim to be Christians, yet practice such things.21
The Bible says that those who are sexually immoral are separated from God
and will not share in God's inheritance upon death.22

Conclusion

Pornography is a big problem in the Christian Church, because it
results in Christians who are double-minded23—wanting
to have one foot in heaven and the other in hell. Pornography
is so insidious because it destroys our purity of mind and makes our
consciences corrupt, being unable to discern the true will of God. For
one who is married, pornography is tantamount to adultery, since Jesus
said one who "looks at a woman with lust for her has already committed
adultery with her in his heart." The Bible says that we the temple of
the Holy Spirit and that we are to be transformed by the experience—to
renew our minds to know the perfect will of God for our lives.

And do not be conformed to this world, but be transformed by the renewing
of your mind, so that you may prove what the will of God is, that which is
good and acceptable and perfect. (Romans 12:2)

References

Do you not know that the wicked will not inherit the
kingdom of God? Do not be deceived: Neither the sexually immoral nor
idolaters nor adulterers nor male prostitutes nor homosexual offenders (1
Corinthians 6:9)Before they had gone to bed, all the men from every part of the city of
Sodom--both young and old--surrounded the house. They
called to Lot, "Where are the men who came to you tonight? Bring them
out to us so that we can have sex with them." Lot went
outside to meet them and shut the door behind him and said,
"No, my friends. Don't do this wicked thing. (Genesis 19:4-7)While they were enjoying themselves, some of the wicked men of the city
surrounded the house. Pounding on the door, they shouted to the old man
who owned the house, "Bring out the man who came to your house so we
can have sex with him." The owner of the house went
outside and said to them, "No, my friends, don't be so vile. Since
this man is my guest, don't do this disgraceful thing. (Judges 19:22-23)In a similar way, Sodom and Gomorrah and the surrounding towns gave
themselves up to sexual immorality and perversion. They serve as an
example of those who suffer the punishment of eternal fire. (Jude 1:7)Therefore God gave them over in the sinful desires of their hearts to
sexual impurity for the degrading of their bodies with one another. They exchanged the truth of God for a lie, and worshiped and
served created things rather than the Creator--who is forever praised.
Amen. Because of this, God gave them over to shameful lusts.
Even their women exchanged natural relations for unnatural ones. In the same way the men also abandoned natural relations with women
and were inflamed with lust for one another. Men committed indecent acts
with other men, and received in themselves the due penalty for their
perversion. (Romans 1:24-27)

"Anyone who has sexual relations with an
animal must be put to death. (Exodus 22:19)
"Cursed is the man who has sexual relations with any animal."
Then all the people shall say, "Amen!" (Deuteronomy 27:21)

"'No one is to approach any close relative to have
sexual relations. I am the LORD. Do not dishonor
your father by having sexual relations with your mother. She is your
mother; do not have relations with her. Do not
have sexual relations with your father's wife; that would dishonor your
father. Do not have sexual relations with your
sister, either your father's daughter or your mother's daughter, whether
she was born in the same home or elsewhere. Do not
have sexual relations with your son's daughter or your daughter's
daughter; that would dishonor you. Do not have
sexual relations with the daughter of your father's wife, born to your
father; she is your sister. Do not have sexual
relations with your father's sister; she is your father's close relative.
Do not have sexual relations with your mother's
sister, because she is your mother's close relative. Do not dishonor your father's brother by approaching his wife to
have sexual relations; she is your aunt. Do not
have sexual relations with your daughter-in-law. She is your son's wife;
do not have relations with her. Do not have
sexual relations with your brother's wife; that would dishonor your
brother. Do not have sexual relations with both a
woman and her daughter. Do not have sexual relations with either her son's
daughter or her daughter's daughter; they are her close relatives. That is
wickedness. Do not take your wife's sister as a
rival wife and have sexual relations with her while your wife is living.'"
(Leviticus 18:6-18)
"Cursed is the man who sleeps with his sister, the daughter of his
father or the daughter of his mother." Then all the people shall say,
"Amen!" Cursed is the man who sleeps
with his mother-in-law." Then all the people shall say,
"Amen!" (Deuteronomy 27:22-23)

"For out of the heart come evil thoughts, murders,
adulteries, fornications, thefts, false witness, slanders. (Matthew 15:19)
"For from within, out of the heart of men, proceed the evil thoughts,

"We were not born of fornication; we have one Father, even God." (John

but that we write to them that they abstain from things contaminated by
idols and from fornication and from what is strangled and from blood. (Acts
15:20)
that you abstain from things sacrificed to idols and from blood and from
things strangled and from fornication; if you keep yourselves free from such
things, you will do well. Farewell." (Acts 15:29)
"But concerning the Gentiles who have believed, we wrote, having
decided that they should abstain from meat sacrificed to idols and from
blood and from what is strangled and from fornication." (Acts 21:25)
Or do you not know that the unrighteous shall not inherit the kingdom of
God? Do not be deceived; neither fornicators, nor idolaters, nor adulterers,
nor effeminate, nor homosexuals, (1 Corinthians 6:9)
Let marriage be held in honor among all, and let the marriage bed be
undefiled; for fornicators and adulterers God will judge. (Hebrews 13:4)

"You shall not commit adultery. (Exodus 20:14)
"You shall not commit adultery. (Deuteronomy 5:18)
"You shall
not covet your neighbor's wife. You shall not set your desire on your
neighbor's house or land, his manservant or maidservant, his ox or donkey,
or anything that belongs to your neighbor." (Deuteronomy 5:21)
"'Do
not have sexual relations with your neighbor's wife and defile yourself
with her. (Leviticus 18:20)
But a man who commits adultery lacks judgment; whoever does so destroys
himself. (Proverbs 6:32)

But if out in the country a man happens to meet a girl pledged
to be married and rapes her, only the man who has done this shall
die. (Deuteronomy 22:25)

Let us behave decently, as in the daytime, not in orgies
and drunkenness, not in sexual immorality and debauchery, not in dissension
and jealousy. (Romans 13:13)
The acts of the sinful nature are obvious: sexual immorality, impurity and
debauchery; idolatry and witchcraft; hatred, discord, jealousy, fits of rage,
selfish ambition, dissensions, factions
and envy; drunkenness, orgies, and the like. I warn you, as I did before, that
those who live like this will not inherit the kingdom of God. (Galatians 5:19-21)
For you have spent enough time in the past doing what pagans choose to
do--living in debauchery, lust, drunkenness, orgies, carousing and detestable
idolatry. (1 Peter 4:3)

"'If a man commits adultery with another
man's wife--with the wife of his neighbor--both the adulterer and the
adulteress must be put to death. If a man sleeps
with his father's wife, he has dishonored his father. Both the man and the
woman must be put to death; their blood will be on their own heads. If a man sleeps with his daughter-in-law, both of
them must be put to death. What they have done is a perversion; their
blood will be on their own heads. If a man lies
with a man as one lies with a woman, both of them have done what is
detestable. They must be put to death; their blood will be on their own
heads. If a man marries both a woman and her
mother, it is wicked. Both he and they must be burned in the fire, so that
no wickedness will be among you. If a man has
sexual relations with an animal, he must be put to death, and you must
kill the animal. If a woman approaches an animal
to have sexual relations with it, kill both the woman and the animal. They
must be put to death; their blood will be on their own heads. If a man marries his sister, the daughter of either his
father or his mother, and they have sexual relations, it is a disgrace.
They must be cut off before the eyes of their people. He has dishonored
his sister and will be held responsible. If a man
lies with a woman during her monthly period and has sexual relations with
her, he has exposed the source of her flow, and she has also uncovered it.
Both of them must be cut off from their people. Do not have sexual relations with the sister of either your mother
or your father, for that would dishonor a close relative; both of you
would be held responsible. If a man sleeps with
his aunt, he has dishonored his uncle. They will be held responsible; they
will die childless. If a man marries his
brother's wife, it is an act of impurity; he has dishonored his brother.
They will be childless.'" (Leviticus 20:10-21)

'You shall not covet your neighbor's wife, and you shall not desire your
neighbor's house, his field or his male servant or his female servant, his
ox or his donkey or anything that belongs to your neighbor.' (Deuteronomy
5:21)

Therefore God gave them over in the lusts of their hearts to impurity, so
that their bodies would be dishonored among them... For this reason God gave
them over to degrading passions; for their women exchanged the natural
function for that which is unnatural, and in the same way also the men
abandoned the natural function of the woman and burned in their desire
toward one another, men with men committing indecent acts and receiving in
their own persons the due penalty of their error. (Romans 1:24-27)
Therefore do not let sin reign in your mortal body so that you obey its
lusts, and do not go on presenting the members of your body to sin as
instruments of unrighteousness; but present yourselves to God as those alive
from the dead, and your members as instruments of righteousness to God. (Romans
6:12-13)
Now flee from youthful lusts and pursue righteousness, faith, love and
peace, with those who call on the Lord from a pure heart. (2 Timothy
2:22)
For we also once were foolish ourselves, disobedient, deceived, enslaved
to various lusts and pleasures, spending our life in malice and envy,
hateful, hating one another. (Titus 3:3)
As obedient children, do not be conformed to the former lusts which were
yours in your ignorance, (1 Peter 1:14)
For the time already past is sufficient for you to have carried out the
desire of the Gentiles, having pursued a course of sensuality, lusts,
drunkenness, carousing, drinking parties and abominable idolatries. (1
Peter 4:3)
These are grumblers, finding fault, following after their own lusts; they
speak arrogantly, flattering people for the sake of gaining an advantage. (Jude
1:16)
For speaking out arrogant words of vanity they entice by fleshly desires,
by sensuality, those who barely escape from the ones who live in error,
(2 Peter 2:18)
Among them we too all formerly lived in the lusts of our flesh, indulging
the desires of the flesh and of the mind, and were by nature children of
wrath, even as the rest. (Ephesians 2:3)

Beloved, I urge you as aliens and strangers to abstain from fleshly lusts
which wage war against the soul. (1 Peter 2:11)

But each one is tempted when he is carried away and enticed by his own
lust. Then when lust has conceived, it gives birth to sin; and when sin is
accomplished, it brings forth death. (James 1:14-15)

"I, the LORD, search the heart, I test the mind, Even to give to each man
according to his ways, According to the results of his deeds. (Jeremiah
17:10)
'And I will kill her children with pestilence, and all the churches will
know that I am He who searches the minds and hearts; and I will give to each
one of you according to your deeds. (Revelation 2:23)

Set your mind on the things above, not on the things that are on earth. (Colossians
3:2)

For those who are according to the flesh set their minds on the things of
the flesh, but those who are according to the Spirit, the things of the
Spirit. For the mind set on the flesh is death, but the mind set on the
Spirit is life and peace, because the mind set on the flesh is hostile
toward God; for it does not subject itself to the law of God, for it is not
even able to do so, and those who are in the flesh cannot please God. (Romans
8:5-8)

To the pure, all things are pure; but to those who are defiled and
unbelieving, nothing is pure, but both their mind and their conscience are
defiled. (Titus 1:15)

And do not be conformed to this world, but be transformed by the renewing
of your mind, so that you may prove what the will of God is, that which is
good and acceptable and perfect. (Romans 12:2)

Do you not know that you are a temple of God, and that
the Spirit of God dwells in you? If any man destroys the temple of God, God
will destroy him, for the temple of God is holy, and that is what you are. (1
Corinthians 3:16-17)

"Food for the stomach and the stomach for food"--but God will
destroy them both. The body is not meant for sexual immorality, but for
the Lord, and the Lord for the body. (1 Corinthians 6:13)

Flee from sexual immorality. All other sins a man commits are outside
his body, but he who sins sexually sins against his own body. Do you not know that your body is a temple of the Holy
Spirit, who is in you, whom you have received from God? You are not your
own; you were bought at a price. Therefore honor God
with your body. (1 Corinthians 6:18-20)

I have written you in my letter not to associate with sexually immoral
people-- not at all meaning the people of this world
who are immoral, or the greedy and swindlers, or idolaters. In that case
you would have to leave this world. But now I am
writing you that you must not associate with anyone who calls himself a
brother but is sexually immoral or greedy, an idolater or a slanderer, a
drunkard or a swindler. With such a man do not even eat. (1 Corinthians
5:9-11)

The acts of the sinful nature are
obvious: sexual immorality, impurity and debauchery; idolatry and
witchcraft; hatred, discord, jealousy, fits of rage, selfish ambition,
dissensions, factions and envy; drunkenness, orgies, and the like. I warn
you, as I did before, that those who live like this will not inherit the
kingdom of God. (Galatians 5:19-21)
Be imitators of God, therefore, as dearly loved children and live a life
of love, just as Christ loved us and gave himself up for us as a fragrant
offering and sacrifice to God. But among you there must not be even a hint
of sexual immorality, or of any kind of impurity, or of greed, because
these are improper for God's holy people. Nor should there be obscenity,
foolish talk or coarse joking, which are out of place, but rather
thanksgiving. For of this you can be sure: No immoral, impure or greedy
person--such a man is an idolater--has any inheritance in the kingdom of
Christ and of God. (Ephesians 5:1-5)
Put to death, therefore, whatever belongs to your earthly nature: sexual
immorality, impurity, lust, evil desires and greed, which is idolatry.
Because of these, the wrath of God is coming. (Colossians 3:5-6)
It is God's will that you should be sanctified: that you should avoid
sexual immorality; that each of you should learn to control his own body
in a way that is holy and honorable, not in passionate lust like the
heathen, who do not know God; and that in this matter no one should wrong
his brother or take advantage of him. The Lord will punish men for all
such sins, as we have already told you and warned you. For God did not
call us to be impure, but to live a holy life. (1 Thessalonians 4:3-7)
Marriage should be honored by all, and the marriage bed kept pure, for God
will judge the adulterer and all the sexually immoral. (Hebrews 13:4)
He who overcomes will inherit all this, and I will be his God and he will
be my son. But the cowardly, the unbelieving, the vile, the murderers, the
sexually immoral, those who practice magic arts, the idolaters and all
liars--their place will be in the fiery lake of burning sulfur. This is
the second death." (Revelation 21:7-8)
"Blessed are those who wash their robes, that they may have the
right to the tree of life and may go through the gates into the city. Outside are the dogs, those who practice magic arts,
the sexually immoral, the murderers, the idolaters and everyone who loves
and practices falsehood. "I, Jesus, have sent my
angel to give you this testimony for the churches. I am the Root and the
Offspring of David, and the bright Morning Star." (Revelation
22:14-16)

If any of you lacks wisdom, he should ask God, who gives
generously to all without finding fault, and it will be given to him. But when
he asks, he must believe and not doubt, because he who doubts is like a wave
of the sea, blown and tossed by the wind. That man should not think he will
receive anything from the Lord; he is a double-minded man, unstable in all he
does. (James 1:5-8)
Come near to God and he will come near to you. Wash your hands, you sinners,
and purify your hearts, you double-minded. (James 4:8)
